要約
(EN)
An oil pressure feed passage (28) of an ignition advance chamber (18) and an oil pressure feed passage (29) of an ignition delay chamber (19) are provided with check valves (30, 31), respectively, for preventing the back flows of oil from the chambers (18, 19). The oil pressure feed passages (28, 29) of the respective chambers (18, 19) are provided with drain passages (32, 33), respectively, for bypassing the check valves (30, 31). The drain passages (32, 33) are equipped with drain switching valves (34, 35), respectively. An oil pressure control valve (21) for controlling the oil pressures to be fed to the ignition advance chamber (18) and the ignition delay chamber (19) is integrated with a drain switching control function (38) for controlling the oil pressures to be individually fed to the drain switching valves (34, 35). The point that the VCT responding rate is abruptly changed by switching the ON/OFF of the drain switching valves (34, 35) is learned to improve the control characteristics of the region near that point, at which the VCT responding rate is abruptly changed.

Un passage d'alimentation de pression d'huile (28) d'une chambre d'avance à l'allumage (18) et un passage d'alimentation de pression d'huile (29) d'une chambre de retard à l'allumage (19) sont équipés de clapets de non-retour (30, 31), respectivement, pour empêcher les reflux d'huile à partir des chambres (18, 19). Les passages d'alimentation de pression d'huile (28, 29) des chambres respectives (18, 19) sont munis de passages de purge (32, 33), respectivement, pour dériver les clapets de non-retour (30, 31). Les passages de purge (32, 33) sont équipés de soupapes de commutation de purge (34, 35), respectivement. Une soupape de commande de pression d'huile (21) pour commander les pressions d'huile devant être amenées jusqu'à la chambre d'avance à l'allumage (18) et la chambre de retard à l'allumage (19) est intégrée avec une fonction de commande de commutation de purge (38) pour commander les pressions d'huile devant être amenées individuellement jusqu'aux soupapes de commutation de purge (34, 35). Le point au niveau duquel la vitesse de réponse VCT est abruptement changée en commutant le bouton Marche/Arrêt des soupapes de commutation de purge (34, 35) est considéré comme améliorant les caractéristiques de commande de la région à proximité de ce point, au niveau duquel la vitesse de réponse VCT est abruptement changée.

 進角室(18)の油圧供給油路(28)と遅角室(19)の油圧供給油路(29)に、それぞれ各室(18,19)からのオイルの逆流を防止する逆止弁(30,31)を設けると共に、各室(18,19)の油圧供給油路(28,29)に、それぞれ逆止弁(30,31)をバイパスするドレーン油路(32,33)を並列に設け、各ドレーン油路(32,33)に、それぞれドレーン切替弁(34,35)を設ける。進角室(18)と遅角室(19)に供給する油圧を制御する油圧制御弁(21)に、各ドレーン切替弁(34,35)に供給する油圧を制御するドレーン切替制御機能(38)を一体化する。ドレーン切替弁(34,35)の開弁/閉弁の切り替えによりVCT応答速度が急変する点を学習し、VCT応答速度急変点付近の領域の制御特性を向上させる。
